INTRODUCTIONT hermal Management is becoming more important as thedensity of electronic components in modern printed circuitboards (PCBs), as well as the applied power, continues toincrease. Both factors lead to higher temperatures ofindividual components and of the entire , every electrical component in an assembly has tobe used within its prescribed operating temperature limitsdue to its material properties and reliability aspects. In thisapplication note, experimental results are provided in orderto prevent overheating of electronic devices such assurface-mount ELECTRICAL LOSS AND HEAT TRANSFERHeat is dissipated in the resistor by electrical loss (Jouleeffect), resulting in a temperature rise.
